One component of a robust solution that, when paired with a base unit (part 89008 or 89009, sold separately), extends your VGA & 3.5mm audio signals up to 300 meters over a Cat 5E UTP cable, & distributes the signal to up to 4 monitors, projectors, or displays. Ideal for applications when your VGA monitor needs to be placed beyond the average 30 meter VGA cable limitation, and/or you want to split the signal to multiple displays.
